Is it both food and drink they will make more money out of? or just food? just drink? Both.any special type of food? Not really. Just the sort of food with accompanying drink one might have for lunch. salty? traditional? May include some traditional dishes as well. special type of drink? like beer? Some beer and wine might be included, but I think most of the drinks are non-alcoholic.

The music will keep them at the table longer? No.Is there some reason they can't leave while the music's playing? No. They can leave and do it.Is the music being used to time the serving of the food/drink? No. There's just some music played in the background.

1) In 1735, German composer Georg Philipp Telemann published a collection of rather unconnected pieces under the name Tafelmusik (table music). This collection contributed much to Telemann's popularity, and so one may assume, also to his income.

2) The idea to increase the income with the help of "table music" (or music for the table) was re-used last year by a group of people. They played music while other people were eating, and, thus, sold more food and drinks.

3) It has not yet been found out, how exactly they managed this. The people who were eating in this place neither got more hungry from the music, not did they stay longer or consume more than the usual quantity.

To find out: - Where does this take place? - How do they manage to sell more food? - What does this have to do with the music?

Did they go to the place and eat because they liked the music? Noish.Would they not had come there if it were not for the music? Yope. If there was no music, they might not have come there, but the effect of the music is indirect.did the music mask some noise? No, but somewhat the right forest. (just somewhat, however)like from a building site? No.

Did the people eat more than they would've without the music (even if that wasn't more than the usual quantity)? No or Yes, depending on what you mean.Did they feed the musicians? No.Was this for only one meal? No.

Is there a scientific principal at work here? You mean, whether the principal of this institution is a scientist? This may well be the case, but I'm not sure. Anyway, you're probably on to something with your question.

Pavlov? Human behavior is full of Pavlov-like effects (aka prejudice), so there might be one involved here as well, but it is probably too misleading to dig deeper into that.Did the same people eat multiple meals there? I can't answer otherwise but yope. (and it could help you a lot to explore why)
